Decentralised web annotation

ABSTRACT

Annotations relating to web sites may be based on blog posts relating to the web sites. A user viewing a web site may concurrently view related blog posts about the web site. More particularly, in one implementation, a method includes detecting when a user visits a web page and receiving, in response to the detection, a group of blog posts that link to the web page. The method further includes displaying an indication of the group of blog posts to the user while the user is visiting the web site.

BACKGROUND

A. Field of the Invention

Implementations consistent with the principles of the invention relategenerally to information dissemination and, more particularly, todecentralized techniques for allowing web annotation.

B. Description of Related Art

The World Wide Web (“web”) contains a vast amount of information. Whenbrowsing a particular document on the web, such as a web page, users aretypically limited to only viewing the web page itself. Supplementaryinformation, such as information provided by other web sites or otherweb users about the particular site being viewed, can be difficult toeasily view. For example, assume that a user is viewing themanufacturer's web page relating to a product the user is interested inpurchasing. To see other web pages reviewing or commenting on theproduct, the user may need to separately search for other web sitespages that contain formal reviews or other comments about the product.

One attempt to allow users to annotate particular web pages withcomments that could be viewed by other users when visiting the web pagewas the “Third Voice” browser plug-in. Third Voice allowed users to postpublic notes about a web site that could then be seen by other ThirdVoices users that later visit the web site. One problem suffered by thisproduct was that comments about a web site were often “low quality”comments that were spammy and/or inappropriate.

SUMMARY

One aspect is directed to a method that includes detecting when a uservisits a web site; receiving, in response to the detection, a group ofblog posts that link to the web site; and displaying an indication ofthe group of blog posts to the user while the user is visiting the website.

Another aspect is directed to a method including detecting when a uservisits a web site and submitting, in response to the detection, a searchquery to a search engine. The search query requests documents relevantto the web site. The method further includes receiving documents inresponse to the submitted search query and displaying an indication ofthe documents to the user while the user is visiting the web site.

Yet another aspect is directed to a system including a blog searchengine and a client device connected to the blog search engine over anetwork. The client device includes a software component configured todisplay web sites to users and to concurrently determine and displayportions of blog posts that link to a currently displayed web site. Theblog posts are determined based on a query to the blog search engine forblog posts linking to the currently displayed web site.

DETAILED DESCRIPTION

The following detailed description of the invention refers to theaccompanying drawings. The detailed description does not limit theinvention.

Overview

As described herein, an easy entry point is provided through which usersmay annotate web pages and see other users' annotations. The annotationsmay be taken from blog posts relating to the web page being annotated.

A “blog,” which is a shortened term for weblog, may be defined as awebsite through which an individual or a group generates text,photographs, video, audio files, and/or links, typically but not alwayson a daily or otherwise regular basis. Authoring a blog, maintaining ablog or adding an article to an existing blog is called “blogging”.Individual articles on a blog are called “blog posts”, “posts”, or“entries”. The person who posts these entries is called a “blogger”.Frequently, bloggers generate posts that comment on and/or link to otherweb pages.

Consistent with an aspect of the invention, a user viewing a web sitemay concurrently view blog posts about the web site. By using blog postsas annotation information for a web site, inappropriate or spammycomments about a web site can be reduced, as blog posts tend to have aninherent level of seriousness associated with them and the blog postscan be ranked or otherwise filtered based on the quality of theunderlying blog.

System Description

FIG. 1 is an exemplary diagram of a system 100 in which conceptsconsistent with the principles of the invention may be implemented.System 100 may include clients 110 coupled to servers 120 and 122 via anetwork 140. Network 140 may include a local area network (LAN), a widearea network (WAN), a telephone network, such as the Public SwitchedTelephone Network (PSTN), an intranet, the Internet, or a combination ofnetworks. Two clients 110 and two servers 120 and 122 have beenillustrated as connected to network 140 for simplicity. In practice,there may be more clients and/or servers. Also, in some instances, aclient may perform the functions of a server and a server may performthe functions of a client.

Clients 110 may include a device, such as a wireless telephone, apersonal computer, a personal digital assistant (PDA), a lap top, oranother type of computation or communication device, a thread or processrunning on one of these devices, and/or an object executable by one ofthese devices. Clients 110 may include software such as a browser 115that is used to access and display web pages from a web server such asserver 120 or 122. Browser 115 may include, for example, the Firefox™browser. Clients 110 may additionally include a software componentdesigned to interact with browser 115 to allow users to annotate andview annotations relating to web pages. This software component will bereferred to herein as DCom (Distributed Web Comments) component 118.DCom component 118 may be, for example, in some implementations, a webbrowser plugin or extension. In other implementations, DCom component118 may be a separate program on client 110.

Servers 120 and 122 may provide services on behalf of clients 110, andmay include, for example, a web server, a file server, or an applicationserver. In one implementation, server 120 may include a search engine125 usable by clients 110. Search engine 125 may be a query-baseddocument search engine. Search engine 125 may be designed to returnlinks to web pages that include information relevant to a search query.Search engine 125 may be a specialized search engine, such as a blogsearch engine designed to return blog posts or links that are relevantto user's search query.

Search engine 125 may respond to user search queries based on documentsstored in database 135. The documents stored in database 135 may includeweb pages that are connected to network 140 and that were previouslycrawled and indexed by search engine 125. When search engine 125 is ablog search engine, the documents stored in database 135 may be indexedblog posts or blogs. Although shown as a single database in FIG. 1,database 135 could be distributed over multiple storage devices.Similarly, although shown as a single device in FIG. 1, servers 120/122and search engine 125 may be implemented in a distributed manner overmultiple computing devices.

FIG. 2 is an exemplary diagram of a client 110, server 120, or server122, referred to as computing device 200, according to an implementationconsistent with the principles of the invention. Computing device 200may include a bus 210, a processor 220, a main memory 230, a read onlymemory (ROM) 240, a storage device 250, an input device 260, an outputdevice 270, and a communication interface 280. Bus 210 may include apath that permits communication among the components of computing device200.

Processor 220 may include any type of processor, microprocessor, orprocessing logic that may interpret and execute instructions. Mainmemory 230 may include a random access memory (RAM) or another type ofdynamic storage device that stores information and instructions forexecution by processor 220. ROM 240 may include a ROM device or anothertype of static storage device that stores static information andinstructions for use by processor 220. Storage device 250 may include amagnetic and/or optical recording medium and its corresponding drive.

Input device 260 may include a mechanism that permits a user to inputinformation to computing device 200, such as a keyboard, a mouse, a pen,voice recognition and/or biometric mechanisms, etc. Output device 270may include a mechanism that outputs information to the user, includinga display, a printer, a speaker, etc. Communication interface 280 mayinclude any transceiver-like mechanism that enables computing device 200to communicate with other devices and/or systems. For example,communication interface 280 may include mechanisms for communicatingwith another device or system via a network, such as network 140.

Software components of system 100, such as search engine 125, browser115, and DCom component 118 may be stored in a computer-readable medium,such as memory 230. A computer-readable medium may be defined as one ormore physical or logical memory devices and/or carrier waves. Thesoftware instructions defining the software components may be read intomemory 230 from another computer-readable medium, such as data storagedevice 250, or from another device via communication interface 280. Thesoftware instructions contained in memory 230 cause processor 220 toperform processes that will be described later. Alternatively, hardwiredcircuitry may be used in place of or in combination with softwareinstructions to implement processes consistent with the presentinvention. Thus, implementations consistent with the principles of theinvention are not limited to any specific combination of hardwarecircuitry and software.

Operation of DCom Component 118

FIG. 3A is a diagram illustrating an exemplary graphical user interface300 for a web browser 115 presented to a client 110 using DCom component118. User interface 300 may include menu section 305, navigation toolbar310, a web page display section 315, and a status bar 320. Menu section305 presents a number of menus to the user through which the user maycontrol the operation of web browser 115. Navigation toolbar 310 mayinclude one or more controls through which the user can control webbrowser 115 when navigating the web, such as “forward” and “back”buttons and an input box to enter uniform resource locators (URLs). Webpage display section 315 may present the web page currently beingvisited and status bar 320 may display status information relating tothe operation of web browser 115.

Status bar 320 may additionally display an indication of how highly theweb site or web page currently being visited (i.e., the site in displaysection 315) is annotated. In the example shown in FIG. 3A, thisfunction is performed via a “buzz” icon 325, which is illustrated as agraphical meter. Buzz icon 325 may be displayed in status bar 320 onbehalf of or under the control of DCom component 118. Buzz icon 325 maychange based on a “buzz rating” determined based on the annotationsassociated with the current web site. For example, when a user isvisiting a web site with no associated annotations, buzz icon 325 maynot be shown or may be shown as an graphical bar or meter with an emptyor zero reading. When a user is visiting a web site with annotations,buzz icon 325 may change to reflect the number, quality, and/or temporalrelevance of the annotations. For example, a user visiting a site with alot of annotations may see a buzz icon with a full meter reading. Insome implementations, the size or color of buzz icon 325 may alsochange. The particular design used by buzz icon 325 to reflect theannotations for a site is not critical. In general, buzz icon 325 may bedesigned so that sites with a high “buzz” rating are given a “stronger”icon, where the buzz rating may be based on some combination of thenumber, quality, or timeliness of the annotations associated with theweb site. In some implementations, timeliness of the annotations for asite may be based on timeliness relative to the last time the uservisited a site. In other words, buzz icon 325 may indicate how much theannotations for the site have changed since the last time the uservisited the site.

Additionally, in some implementations, the functionality of buzz icon325 may be presented to the user in sections of browser 115 other thanstatus bar 320.

FIG. 3B is a diagram illustrating a second exemplary graphical userinterface 350 for a web browser 115 presented to a client 110 using DComcomponent 118. Graphical user interface 350 is similar to graphical userinterface 300, except that a sidebar 355 is additionally shown withinweb page display section 315. Sidebar 355 may be displayed in responseto the user indicating an interest in the annotations for a site. Forexample, the user may be able to toggle sidebar 355 by clicking on buzzicon 325, by typing a specific keyboard combination, or by selecting thesidebar from menu 305.

Sidebar 355 may display the annotations, portions of the annotations, orlinks to the annotations associated with a particular site. Sidebar 355may additionally allow the user to post comments to his/her blog aboutthe site.

As shown in the example of FIG. 3B, sidebar 355 displays portions ofthree blog posts, labeled as posts 360-362, that link to the current website. Each blog post 360-362 may include a link (i.e., the underlinedportion), that, when selected by the user, may take the user to the webpage corresponding to the selected blog post. Sidebar 355 mayadditionally include a “more” link 365 that, when selected, causesadditional annotations to be shown, and a “create post” link 367 that,when selected, may provide a convenient entry point through which theuser may create a blog post in their own blog about the web site.

The operation of DCom component 118 in conjunction with browser 115 willnext be described in more detail with reference to the flow charts shownin FIGS. 4-6.

FIG. 4 is a flowchart illustrating exemplary operations through which auser may initially install or configure DCom component 118. The user mayinitially install DCom component 118 at client computer 110 at whichDCom component 118 is to be used (act 401). DCom component 118 may be abrowser plugin, extension, or other browser addon component that isdownloaded from server 120 or 122. In other implementations, DComcomponent 118 may be script or other code that can be downloaded and runby client 110 on an as-needed basis. In still other implementations,DCom component 118 may be a separate application that runs in parallelwith browser 115 at client 110.

When initially running DCom component 118, the user may be queried todetermine whether they have a blog hosted at a site recognized by DComcomponent 118 (act 402). If yes, the user may enter their registrationinformation, such as their username and password, for their blog (act403). This information may be later used to allow the user to post or tobegin a post from within sidebar 355. If the user does not have a bloghosted at a site recognized by DCom component 118, the user may beprompted to determine whether they would like to sign up for a new blog(act 404). If the user decides they would like to sign up for a newblog, a new web page may be opened at a registration page for the newblog.

After the initial installation, login, and/or registration shown in acts401-404, DCom component 118 may execute normally on client 110 (act405). Normal execution of DCom component 118 will be described in moredetail below with reference to FIGS. 5 and 6. After initial installationand registration, acts 401-403 may not need to be performed each timethe user uses client 110.

FIG. 5 is a flow chart illustration exemplary operations that may beperformed during minimized operation of DCom component 118. DComcomponent 118 may monitor the browsing session of the user for changesto the web site or web page the user is viewing (act 501). When DComcomponent 118 detects a new site, or possibly, a new web page within asite, DCom component 118 may obtain the buzz rating, or information thatcan be used to obtain the buzz rating, for the site (acts 502 and 503).The buzz rating is designed to generally reflect the likelihood that auser will want to view the annotations for the site. As previouslymentioned, the buzz rating may be based on some combination of thenumber, quality, or timeliness of the annotations associated with theweb site.

In one implementation, DCom component 118 may calculate the buzz ratingbased on the examination of the annotations (i.e., blog posts) thatcorrespond to a site. The annotations may be obtained by querying a blogsearch engine, such as search engine 125, in a manner that restricts thesearch results to blog posts that link to the current site. For example,queries to the existing Google™ blog search engine of the form “link:<URL>” restricts results to blog posts that link to “URL.” Using theexample web site shown in FIG. 3A, DCom component may submit the query“link: labs.google.com”. The results of this query from search engine125 may include a number of blog posts for this web site“labs.google.com”. Based on the number, timeliness, and/or quality ofthese blog posts, DCom component 118 may generate the buzz rating. Asone example of generating a buzz rating, the buzz rating may be equal tothe number of blog posts returned from search engine 125 that is morerecent than a particular cut-off date (such as the date associated withthe last time the user visited the site).

The buzz rating calculated in act 503 may be presented to the user (act504). For example, the buzz rating may be visually presented to the uservia buzz icon 325. As previously mentioned, buzz icon 325 may bedesigned so that sites with a high “buzz” rating are given a “stronger”(visually more distinctive) icon.

FIG. 6 is a flow chart illustrating exemplary operations that may beperformed during operation of DCom component 118 when the user isviewing the main user interface for DCom component 118 (e.g., when theuser has clicked buzz icon 325 to display sidebar 355). DCom component118 may retrieve the annotations, or links to the annotations, for thecurrent site, such as by querying search engine 125 (act 601). Theannotations may previously have been downloaded by DCom component 118 ingenerating the buzz rating (FIG. 5). In this situation, DCom component118 may not need to re-query search engine 125. The annotations, or apre-selected number of the annotations, may then be displayed to theuser (act 602). In the example shown in FIG. 3B, three annotations forthe current site are shown to the user in sidebar 355. DCom component118 may appropriately respond to user actions in sidebar 355. Forexample, if the user clicks on a link associated with one of theannotations, browser 115 may be directed to display the complete blog orblog post corresponding to the annotation (act 603). In situations wheremore annotations are available, the user may choose to see moreannotations in sidebar 355, such as by selecting the “more” link 355(act 604). Still further, the user may choose to post a comment aboutthe current site by creating a post for their blog (act 605). The usermay initiate their blog post by selecting “create post” link 367. Doingso may, for example, take the user to a web page at which the user maymanage the blog and, in particular, create a new post for the blog. Thenew blog post may be preset to include a link back to the current site(i.e., “labs.google.com” in the example shown in FIG. 3B).

Exemplary Additional User Interfaces

As mentioned, the user interface shown in FIGS. 3A and 3B are exemplary.Additional exemplary user interfaces that may be provided by DComcomponent 118 will now be described with reference to FIGS. 7A-7D. Inthis exemplary implementation of DCom component 118, DCom component 118may communicate with the user through popup windows instead of throughthe sidebar shown in FIG. 3B. In some implementations, how DComcomponent 118 communicates with the user, such as a popup window orbrowser sidebar windows, may be a user-configurable parameter.

FIG. 7A is a diagram illustrating an exemplary graphical user interface700 for a web browser 115 presented to a client 110 using DCom component118. Graphical user interface 700 may include a buzz icon 725 thatfunctions similarly to buzz icon 325. Instead of sidebar 355, graphicaluser interface 700 may include a popup window 755 that displays a numberof annotations for the site currently being viewed. Popup window 755 mayinclude a header link 760 for each annotation, a “show lots more” link765, and an “add comment” link 767. Header link 760, when selected bythe user, may open a web browsing window at the blog post correspondingto the header. Show lots more link 765 and add comment link 767 mayfunction similarly to “more” link 365 and “create post” link 367,respectively. Specifically, show lots more link 765, when selected,causes additional annotations for the web site, if available, to bedisplayed in popup window 755. Add comment link 767 may provide aconvenient entry point through which the user may create a blog post intheir own blog about the web site.

FIG. 7B is a diagram illustrating an exemplary graphical user interface702 in which popup window 755 is shown as a smaller popup window. Usersmay switch between the larger version of popup window 755 and thesmaller version of popup window 755 using standard sizing icons in theupper right corner of the window.

FIG. 7C is a diagram illustrating an exemplary popup dialog 704 that maybe provided to the user when the user selects “add comment” 767 linkwithout having a registered blog. As shown, dialog 704 provides fieldsthrough which users may enter their blog username and password.Additionally, dialog 704 provides a link through which the user mayregister for a new blog and a link through which the user may recover aforgotten password.

FIG. 7D is a diagram illustrating an exemplary dialog 706 that may beprovided to the user when the user selects “add comment” link 767 andthe user has registered their blog. As shown, dialog 706 provides anarea 770 in which the user may compose their blog post. Area 770 may bepre-populated with a link back to the web page currently being viewed.In the example shown in FIG. 7D, this link is illustrated as theunderlined text “Read . . . ”. When the user is ready to publish theblog post to his/her blog, the user may select “publish” button 772.

Although DCom component 118 was generally described above as receivingand operating on web annotations from a blog search engine, DComcomponent 118 may more generally operate to receive annotations fromother search engines in which the search results are in someway limitedby the site or web page currently being visited. More generally, DComcomponent 118 may operate to receive annotation information from anyother website that links to and in someway comments on the current website. The linking websites may include websites that in someway providereviews, commentary, critiques, or feedback to the current website orwebpage. Additionally, instead of receiving annotations from a searchengine, DCom component 118 may receive the annotations from a differentserver, such as an annotation server designed to operate specificallywith DCom component 118.

CONCLUSION

Techniques for providing decentralized user web annotations weredescribed above. The web annotations may be based on blog posts,providing the system with an existing initial base of web annotations.Additionally, because the annotations may be received from a blog searchengine, which may already provide quality and/or spam filtering controlson the blogs it is indexing, the annotations are likely to be lessspammy or inappropriate relative to existing web annotation systems.
